Koheras IR single frequency fiber lasers

Koheras single-frequency lasers are longitudinally single-mode and offer extremely low phase and intensity noise levels. Available in the erbium, ytterbium, or thulium wavelength ranges and with frequency conversion to many other bands.
Reliability is our highest priority and the all-fiber DFB design ensures robust and reliable operation for thousands of hours.

Koheras lasers are extremely stable and mode-hop-free – even under changing environmental conditions. You can also get shot noise-limited solutions for applications demanding extra low-intensity noise levels.
